Now that the driver has been merged, I've merged the platform patches up
to this point.

Unfortunately, sending PRs to arm-soc that merge in branches from other
trees has failed in the past, so I won't be able to merge 6 and 7 for
4.12.  That said, it's a whole lot less that the various downstream
kernels will need to pull for the Pi3 than they've been carrying around
until now :)
